Whether S12: receiving the first transaction that user terminal is sent, and be empty by first predecessor's Transaction Information of the first transaction The first transaction for determining preparatory trading pit to be deposited is to replace the first kind transaction of predecessor's transaction or do not replace the of predecessor's transaction The transaction of two classes:
If the first transaction is that the second class is traded, S13 is thened follow the steps: the first transaction is stored in preparatory trading pit；
If the first transaction is that the first kind is traded, S14 is thened follow the steps: according to the first transaction of first predecessor's Transaction Information inquiry Predecessor trade whether in preparatory trading pit:
It is to then follow the steps S15: is discarded by first predecessor's transactional marking, and the first transaction is stored in preparatory trading pit In；And
S16: receiving the first confirmation message for being used to confirm the first transaction that user terminal is sent, by the first transaction deposit transaction Pond, and generate the second confirmation message and the other nodes for being sent to block chain that the first transaction has confirmed that；Or, receiving block chain First transaction is stored in trading pit by the second confirmation signal that other nodes are sent；
S17: it after the first transaction is packaged, is handed over according to the first predecessor of the first transaction of first predecessor's Transaction Information inquiry Easily；
S18: it is traded according to the inquiry of predecessor's Transaction Information of the transaction inquired with the presence or absence of a upper predecessor, circulation is worked as Preceding step is until inquiry is traded less than predecessor；
S19: the predecessor's transaction deleting the first predecessor transaction and respectively inquiring.
Specifically, the first transaction that user generates and sends is configured with predecessor's Transaction Information predecessor and discarded letter Cease discard；First predecessor's Transaction Information is the transaction Hash of predecessor's transaction of the first transaction, when the first no predecessor of transaction hands over Predecessor's Transaction Information of Yi Shi, first transaction are configured to sky；Discard information is used to identify the discarded state of transaction；User sends The first confirmation message for confirm the first transaction be the first transaction through user's signature transaction Hash, node A generation the The second confirmation message that one transaction has confirmed that, the second confirmation message are consistent with the first confirmation message；
Indicate that transaction is not discarded when state is false to discard, for expression transaction is discarded when discarded state is true；It is false If there are 100 transaction tx_1~tx_100 in current trading pit in advance, do not trade in trading pit；User's first generate tx_101 and Tx_102, and it is sent to the node A of block chain；Wherein, the predecessor of tx_101 is sky, the predecessor of tx_102 It is hash (tx_60) for hash (tx_80), the predecessor of tx_80, the predecessor of tx_60 is sky；User's first is true Recognize tx_102 it is errorless after, send sig (hash (tx_102)) to the node A of block chain, the second confirmation message and the first confirmation letter Breath is consistent, is also sig (hash (tx_102))；
User's first generates tx_101 and tx_102, and is sent to the node A of block chain；
When node A receives tx_101:
In step s 12, node A receives the tx_101 that user's first is sent, and by the predecessor of tx_101 whether It is to replace the first kind transaction of predecessor's transaction or do not replace what predecessor traded for the empty tx_101 for determining preparatory trading pit to be deposited The transaction of second class:
Since the predecessor of tx_101 is sky, tx_101 is the transaction of the second class, thens follow the steps S13: by tx_101 It is stored in preparatory trading pit.
When node A receives tx_102:
In step s 12, node A receive user's first send tx_102, and by tx_102 and predecessor be The no tx_102 for empty determining preparatory trading pit to be deposited is to replace the first kind transaction or do not replace predecessor's transaction that predecessor trades The second class transaction:
Since the predecessor of tx_102 is hash (tx_80), tx_102 is first kind transaction, is thened follow the steps S14: tx_80 is traded whether in preparatory trading pit according to the predecessor that hash (tx_80) inquires tx_102:
Due to there are 100 transaction tx_1~tx_100, tx_80 in preparatory trading pit in current trading pit in advance, then hold Row step S15: by tx_80 labeled as discarding, the discard of tx_80 is updated to true by false, and tx_102 is stored in advance In first trading pit；And
In step s 16, node A receives the sig (hash (tx_102)) that user's first is sent, and tx_102 is stored in and is traded Pond, and generate first the second confirmation message for having confirmed that of transaction, since the second confirmation message is consistent with the first confirmation message, also for Sig (hash (tx_102)), therefore sig (hash (tx_102)) is sent to other nodes of block chain by node A；Or, node A The second confirmation signal sig (hash (tx_102)) that other nodes of block chain are sent is received, tx_102 is stored in trading pit；
In step S17, node A inquires the first predecessor of tx_102 according to hash (tx_80) after tx_102 is packaged Transaction is hash (tx_80)；
In step S18, node A is according to the inquiry of predecessor's Transaction Information of the transaction inquired with the presence or absence of before upper one Body transaction, circulation current procedures are until inquiry is traded less than predecessor；According to the predecessor of tx_80 inquiry with the presence or absence of upper One predecessor's transaction, the predecessor of tx_80 are hash (tx_60), and the upper predecessor transaction of tx_80 is tx_60；Again It is traded according to the predecessor of tx_60 inquiry with the presence or absence of a upper predecessor, inquires predecessor's transaction less than tx_60, circulation Terminate；
In step S19, node A deletes tx_80 and tx_60.
Prevent transaction return principle are as follows: when another node of block chain, it is assumed that be node B, due to network delay or its Tx_80 is returned to node A by its problem；If tx_102 is not packaged also at this time, node A judges, exists in preparatory trading pit Tx_80, and tx_80 has been labeled as discarding, node A abandons the tx_80 of node B passback；If tx_102 is packaged at this time, hand in advance The tx_80 and tx_60 of Yi Chizhong has been deleted, and node A checks whether node B is consistent with the block height of oneself, due to node A It has been packaged tx_102, and node B is naturally larger than the block height of node B still in tx_80 stage, the block height of node A is returned Degree, node A abandon the tx_80 of node B passback.
Above-described embodiment configures predecessor's Transaction Information by the transaction for preparatory trading pit to be deposited and selects before being replaced Body transaction, when the predecessor to be replaced trades still in preparatory trading pit, the predecessor's transactional marking that will be replaced is discarded, and will The transaction is stored in preparatory trading pit；When receiving the confirmation signal of the transaction, which is stored in trading pit, and, when this When transaction is packaged, the method for all predecessors transaction for deleting the transaction, so that the transaction can modify transaction before entering trading pit Content, and prevent predecessor from trading and return.
Fig. 2 is the flow chart of step S15 in a kind of preferred embodiment of method shown in Fig. 1.As shown in Fig. 2, excellent one It selects in embodiment, step S15 includes:
S151: judge to send the first address of the first transaction and whether the second address for sending the first predecessor transaction be identical:
It is to then follow the steps S152: is discarded by first predecessor's transactional marking, and the first transaction is stored in preparatory trading pit In.
Specifically, it is assumed that the first address for sending tx_102 is identical as the second address of tx_80 is sent；
When node A receives tx_102:
In step S151, node A judge send tx_102 the first address with transmission tx_80 the second address whether phase It is same:
Since the first address for sending tx_102 is identical as the second address of tx_80 is sent, S152 is thened follow the steps: will Tx_80 is labeled as discarding, and tx_102 is stored in preparatory trading pit.
The first predecessor that above-described embodiment prevents different users to be not belonging to oneself from maliciously sending the first transaction replacement Transaction improves the safety of block catenary system, further improves user experience.
Fig. 3 is the flow chart of step S15 in a kind of preferred embodiment of method shown in Fig. 1.As shown in figure 3, excellent one It selects in embodiment, step S15 includes:
S153: trading according to the inquiry of predecessor's Transaction Information of the transaction inquired with the presence or absence of a upper predecessor, circulation Current procedures are until inquiry is traded less than predecessor；
S154: counting the quantity of each predecessor transaction, and adds one to calculate the first summation；
S155: judge whether the first summation is greater than the threshold value of the quantity of predecessor's transaction of pre-configuration:
It is no, then it executes S157: being discarded by first predecessor's transactional marking, and the first transaction is stored in preparatory trading pit；
It is then to execute S156: abandons the first transaction.
Specifically, it is assumed that the threshold value of the quantity of predecessor's transaction of pre-configuration is 3；
In step S153, node A whether there is upper one according to the inquiry of predecessor's Transaction Information of the transaction inquired Predecessor's transaction, circulation current procedures are until inquiry is traded less than predecessor；It whether there is according to the predecessor of tx_80 inquiry Upper predecessor transaction, the predecessor of tx_80 are hash (tx_60), and the upper predecessor transaction of tx_80 is tx_60； It is traded again according to the predecessor of tx_60 inquiry with the presence or absence of a upper predecessor, inquires predecessor's transaction less than tx_60, follow Ring terminates；
In step S154, the quantity of each predecessor transaction is counted, and adds one to calculate the first summation, predecessor's transaction Quantity is 1, and adding first summation of calculating is 2；
In step S155, judge whether the first summation is greater than the threshold value of the quantity of predecessor's transaction of pre-configuration:
Since 2 are not more than 3, S157 is executed: tx_80 being labeled as discarding, and tx_102 is stored in preparatory trading pit.
Above-described embodiment is expounded the present embodiment so that the threshold value of the quantity for the predecessor's transaction being pre-configured is 3 as an example, In more embodiments, other numerical value can also be configured by the threshold value of the quantity of predecessor's transaction according to actual needs, for example, Be configured to 5, be configured to 0 or negative (be not allow for additional predecessor in addition to the first predecessor transaction is outer and trade), it can be achieved that identical Technical effect.
Above-described embodiment, which constrains a transaction, cannot have excessive predecessor's transaction, to prevent certain malicious users from not stopping paying out It delivers easily replacement predecessor transaction and causes preparatory trading pit congestion, to improve the safety of block catenary system, further improve and use Family experience.
Fig. 4 is the flow chart of step S12 in a kind of preferred embodiment of method shown in Fig. 1.As shown in figure 4, excellent one It selects in embodiment, step S12 includes:
S122: judge whether the transaction amount in preparatory trading pit is less than the threshold value that transaction is stored in preparatory trading pit:
It is no, then it executes S124: abandoning first transaction.
Specifically, it is assumed that node A successively receives tx_101 and tx_102, when node A receives tx_101, preparatory trading pit In transaction amount be less than in preparatory trading pit and store the threshold value of transaction, friendship when node A receives tx_102, in preparatory trading pit Easily sum is not less than the threshold value for storing transaction in preparatory trading pit；
When node A receives tx_102:
In step S122, node A judges whether the transaction amount in preparatory trading pit is less than in preparatory trading pit and stores The threshold value of transaction:
It is no, then S124 is executed, tx_102 is abandoned.
In more embodiments, the threshold value that transaction is stored in preparatory trading pit can be configured according to actual needs, it can be achieved that phase Same technical effect.
In a preferred embodiment, the first threshold for the storage duration traded in preparatory trading pit is configured；Monitoring is handed in advance Whether the waiting time of the transaction of Yi Chi is more than the first threshold: being then to delete the transaction.

The transaction replacement principle of above-described embodiment can refer to method shown in FIG. 1, and details are not described herein again.
Fig. 5 is a kind of flow chart for transaction replacement method that one embodiment of the invention provides.As shown in figure 5, in this implementation In example, the present invention provides a kind of transaction replacement method, comprising:
S202: receive user terminal send first transaction, and by first transaction first predecessor's Transaction Information whether be Sky determines that the first transaction of preparatory trading pit to be deposited is the first kind transaction or do not replace predecessor's transaction that replacement predecessor trades The transaction of second class:
If the first transaction is that the second class is traded, S203 is thened follow the steps: the first transaction is stored in preparatory trading pit；
If the first transaction is that the first kind is traded, S204 is thened follow the steps: being handed over according to first predecessor's Transaction Information inquiry first Whether easy predecessor trades in preparatory trading pit:
It is to then follow the steps S205: the first transaction is stored in preparatory trading pit；
S206: the third confirmation signal for being used to confirm the first transaction that user terminal is sent is received, the first transaction deposit is handed over Yi Chi, and generate the 4th confirmation message and the other nodes for being sent to block chain that the first transaction has confirmed that；Or, receiving block chain Other nodes send the 4th confirmation signal, by first transaction be stored in trading pit；
S207: it is replacement that whether first predecessor's Transaction Information by the first transaction, which is empty determining first transaction to be packaged, The first kind transaction of predecessor's transaction or the second class transaction for not replacing predecessor's transaction:
If the first transaction is that the second class is traded, S208 is thened follow the steps: being packaged the first transaction；
If the first transaction is that the first kind is traded, S209 is thened follow the steps: being handed over according to first predecessor's Transaction Information inquiry first Easy the first predecessor transaction；
S210: trading according to the inquiry of predecessor's Transaction Information of the transaction inquired with the presence or absence of a upper predecessor, circulation Current procedures are until inquiry is traded less than predecessor；
S211: the predecessor's transaction deleting the first predecessor transaction and respectively inquiring, and it is packaged the first transaction.
Specifically, the first transaction that user generates and sends is configured with predecessor's Transaction Information predecessor；First predecessor Transaction Information is the transaction Hash of predecessor's transaction of the first transaction, when first transaction no predecessor transaction, first transaction Predecessor's Transaction Information is configured to sky；User send for confirm the third confirmation message of the first transaction for the through user's signature The transaction Hash of one transaction, node A generate the 4th confirmation message that the first transaction has confirmed that, the 4th confirmation message and third confirm Information is consistent；
Assuming that there are 100 transaction tx_201~tx_300 in current trading pit in advance, do not trade in trading pit；User's first Tx_301 and tx_302 is generated, and is sent to the node A of block chain；Wherein, the predecessor of tx_301 is sky, tx_302 Predecessor be hash (tx_280), the predecessor of tx_280 is hash (tx_260), tx_260's Predecessor is sky；After user's first confirms that tx_301 is errorless, sig (hash (tx_301)) is sent to the node A of block chain, Second confirmation message is consistent with the first confirmation message, is also sig (hash (tx_301))；After user's first sends tx_302, it is believed that Tx_280 is only correctly, after user's first confirms that tx_280 is errorless, sends sig (hash (tx_280)) to the node A of block chain, Second confirmation message is consistent with the first confirmation message, is also sig (hash (tx_280))；
User's first generates tx_301 and tx_302, and is sent to the node A of block chain；
When node A receives tx_301:
In step S202, node A receives the tx_301 that user's first is sent, and the predecessor for passing through tx_301 is The no tx_301 for empty determining preparatory trading pit to be deposited is to replace the first kind transaction or do not replace predecessor's transaction that predecessor trades The second class transaction:
Since the predecessor of tx_301 is sky, tx_301 is the transaction of the second class, thens follow the steps S203: by tx_ The 301 preparatory trading pits of deposit；
In step S206, node A receives the sig (hash (tx_301)) that user's first is sent, and the first transaction deposit is handed over Yi Chi, and the 4th confirmation message and the other nodes for being sent to block chain that the first transaction has confirmed that are generated, due to the 4th confirmation Information is consistent with third confirmation message, is also sig (hash (tx_301)), therefore node A sends sig (hash (tx_301)) To other nodes of block chain；Or, node A receives the 4th confirmation signal sig (hash (tx_ that other nodes of block chain are sent 301) tx_301), is stored in trading pit；
In step S207, whether the predecessor that node A passes through tx_301 is that empty determining tx_301 to be packaged is The first kind transaction of replacement predecessor transaction or the second class transaction for not replacing predecessor's transaction:
Since the predecessor of tx_301 is sky, tx_301 is the transaction of the second class, thens follow the steps S208: being packaged tx_ 301。
When node A receives tx_302:
In step S202, node A receives the tx_302 that user's first is sent, and the predecessor for passing through tx_302 is The no tx_302 for empty determining preparatory trading pit to be deposited is to replace the first kind transaction or do not replace predecessor's transaction that predecessor trades The second class transaction:
Since the predecessor of tx_302 is hash (tx_280), tx_302 is first kind transaction, is thened follow the steps S204: tx_280 is traded whether in preparatory trading pit according to the predecessor that hash (tx_280) inquires tx_302:
It is to then follow the steps S205: tx_302 is stored in preparatory trading pit；
In step S206, node A receives the sig (hash (tx_280)) that user's first is sent, and tx_280 is stored in and is traded Pond, and the 4th confirmation message and the other nodes for being sent to block chain that the first transaction has confirmed that are generated, due to the 4th confirmation letter Breath is consistent with third confirmation message, is also sig (hash (tx_280)), therefore sig (hash (tx_280)) is sent to by node A Other nodes of block chain；Or, node A receives the 4th confirmation signal sig (hash (tx_ that other nodes of block chain are sent 280) tx_280), is stored in trading pit；
In step S207, whether the predecessor that node A passes through tx_280 is empty determining first transaction to be packaged It is the first kind transaction for replacing predecessor's transaction or the second class transaction for not replacing predecessor's transaction:
Since the predecessor of tx_280 is hash (tx_260), tx_280 is first kind transaction, is thened follow the steps S209: the first predecessor transaction that tx_280 is inquired according to hash (tx_260) is tx_260；
In step S210, node A whether there is upper one according to the inquiry of predecessor's Transaction Information of the transaction inquired Predecessor's transaction, circulation current procedures are until inquiry is traded less than predecessor；It whether there is according to the predecessor of tx_260 inquiry Upper predecessor transaction, inquires predecessor's transaction less than tx_260, and circulation terminates；
In step S211, node A deletes tx_260, and is packaged the first transaction.
Prevent transaction return principle are as follows: when another node of block chain, it is assumed that be node B, due to network delay or its Tx_260 is returned to node A by its problem；If tx_280 is not packaged also at this time, node A judges, deposits in preparatory trading pit The tx_260 of node B passback is abandoned in tx_260, node A；If tx_280 is packaged at this time, the tx_260 in preparatory trading pit is It deletes, node A checks whether node B is consistent with the block height of oneself, and since node A has been packaged tx_280, and node B still locates In the passback tx_260 stage, the block height of node A is naturally larger than the block height of node B, and node A abandons node B passback tx_260。
Above-described embodiment is traded by the first predecessor of the first transaction and is believed by receiving the first transaction of user terminal transmission It is before replacing the first kind transaction of predecessor's transaction or not replacing that whether breath, which is empty the first transaction for determining preparatory trading pit to be deposited, The second class transaction of body transaction: if the first transaction is that the second class is traded, the first transaction is stored in preparatory trading pit；If first hands over It easily trades, then whether is traded in preparatory trading pit according to the predecessor of the first transaction of first predecessor's Transaction Information inquiry for the first kind In: it is that then the first transaction is stored in preparatory trading pit；The third for confirming the first transaction that user terminal is sent is received to confirm First transaction is stored in trading pit by signal, and is generated the first the 4th confirmation message for having confirmed that of transaction and be sent to block chain Other nodes；Or, the 4th confirmation signal that the other nodes for receiving block chain are sent, is stored in trading pit for the first transaction；Pass through It is to replace the first kind of predecessor's transaction that whether first predecessor's Transaction Information of the first transaction, which is empty determining first transaction to be packaged, Transaction or the second class transaction for not replacing predecessor's transaction: if the first transaction is that the second class is traded, it is packaged the first transaction；If first Transaction is that the first kind is traded, then is traded according to the first predecessor of the first transaction of first predecessor's Transaction Information inquiry；According to being inquired To transaction predecessor's Transaction Information inquiry with the presence or absence of a upper predecessor trade, circulation current procedures until inquiry less than predecessor Transaction；The predecessor's transaction deleting the first predecessor transaction and respectively inquiring, and the method for being packaged the first transaction, are handed over so that transaction enters Yi Chiqian can modify transaction content, and prevent transaction from returning, and, the specified transaction for needing to confirm of user's alternative, into one Step improves user experience.
